Get in touch to suggest a new calculator, report a calculation error or ask us anything else.
Email us at calculadorauniversal@gmail.com. We read every message, in English or in Spanish.
What we can help with
- A calculation error. It’s what we most want to hear about. Tell us what you entered, what you expected and what you got.
- Suggesting a new calculator. Tell us what you need to calculate and how often you do it.
- Accessibility or display problems on your device or browser.
- Exercising your data protection rights (access, rectification, erasure, objection, restriction and portability).
What we can’t do
We don’t give personalized financial, tax, medical or legal advice. The calculators are tools for guidance: for important decisions, talk to a qualified professional.
